The ssh library was designed to be used by programmers needing a working
SSH implementation by the mean of a library. The complete control of the
client is made by the programmer. With libssh, you can remotely execute
programs, transfer files, use a secure and transparent tunnel for your
remote programs. With its Secure FTP implementation, you can play with
remote files easily, without third-party programs others than libcrypto
(from openssl).
